The largest value of MRE can be observed at concentration of particles in filler at around 30%. 
[1]}, [2]}, [3]}, [4]} and the main interactions are dipole magnetic pair interactions, under the influence of which particles shift and form chains [5]}, [6]}. However, even in the case of large concentrations of particles in MAE, as stated in [3]}, the magnetic anisotropy should be taken into account [8]}. It is proposed in [9]}, that at high concentrations particles would not only shift but also rotate if they have a magnetic anisotropy. For MAE with low concentration of magnetically anisotropic particles, the MRE is mainly influenced by the rotation of particles induced by the magnetic field.
